Quest 1949 Journal 88 May 26 El Carrizalito, 1400 ft 5 mi N. Santiago, Baja California long; and, the third section composed of a tunnel entering an enlarged section at the back. There were several hundred Macrotus californicus hanging in the ceiling of the cave, in the third section which flew out into the first section in a steady stream when disturbed. No Macrotus were taken. About 22 spectators gathered to watch the action in the caves. May 27 Lane Location Three. Roadrunners and many Celsiarius and Dipsoaaurus were seen along the road yesterday. Saw a large Crocodile in the bush east of camp yesterday Hunted bats yesterday at dusk and darks. Shot one Myotis californicus at 7:15 flying along a brush fence. Netted two Epistrellus lesperea over the lower water tank after dark. Dr. Benson netted one Corynorhinus there among other bats. The bats were noticeably fewer last night, th population possibly being taken down by the fairly large numbers of bats taken there on previous nights by the group. Species of bats taken at this location to date have been: Macrotus californicus, Myotis calif- orius, Myotis volans, Myotis velifer, Eptesicus fuscus, Pipistrellus hesperna, Laminus, Dasypatema ega, Antrogous minor, and Corynorhinus.
